The Primary SMTP Address Template is Not the Default

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue.
The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime.

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the domain identified for use as the primary SMTP address template by EnabledPrimarySMTPAddressTemplate attribute of the Exchange organization's default e-mail address policy matches the value of the msExchAcceptedDomain attribute of the default accepted domain.

Note:

In Exchange Server 2007, recipient policies (which were part of Exchange Server 2003) are divided into two separate features: accepted domains and e-mail address policies.

E-mail address policies generate the primary and secondary e-mail addresses for your recipients (which include users, contacts, and groups) so they can receive and send e-mail. By default, Microsoft Exchange contains an e-mail address policy that specifies the recipient's alias as the local part of the e-mail address and uses the default accepted domain. The local part of an e-mail address is the name that appears before the at sign (@).

An accepted domain is any Simple Mail Transfer Protocol (SMTP) namespace for which a Microsoft Exchange organization sends or receives e-mail. Accepted domains include those domains for which the Exchange organization is authoritative. An Exchange organization is authoritative when it handles mail delivery for recipients in the accepted domain. Accepted domains also include domains for which the Exchange organization receives mail and then relays it to an e-mail server that is outside the Active Directory directory service forest for delivery to the recipient.

The default accepted domain is the domain name that is associated with outbound messages that have encapsulated addresses, such as IMCEANOTES-user+40OtherSystem@contoso.com, for non-Exchange e-mail system interoperability.

If the Exchange Server Analyzer determines that the domain used by the primary SMTP address template for an e-mail address policy does not match the domain specified by the msExchAcceptedDomain attribute of the default accepted domain, the Exchange Server Analyzer displays a warning.

This warning means that mail addressed to recipients with the non-default SMTP domain address template may not be delivered.

To address this warning, edit the primary SMTP address template of the identified e-mail address policy to the default accepted domain.
